When I first heard about 3D printing, I thought it was a weird choice of words. It is a good word, because it tells a story familiar to people living today, but why not call it home manufacturing or on-site factories, or the like? I’m not sufficiently knowledgable about the history of technology, but is it possible that the printing press was really the first repeatable manufacturing process? We have always build machinery, but did we ever before the printing press have a repeatable process? If not, then this naming is apt.
